RESUMEN
OBJECTIVE To share surgical experience of ossicular chain malformations with CO2 laser.METHODS A retrospective analysis was performed.9 patients with clinical diagnosis of ossicular malformations underwent ossicular reconstruction with CO2 laser-assisted from May 2010 to Mar 2016,the results were evaluated by comparing preoperative and postoperative audiometric outcomes and the rate of postoperative complications.RESULTS 8 cases with complex lesion combining incus and stapes were found intraoperatively,the deformity located on stapes was showed in one case.The mean postoperative air conduction (AC) value was (26.53 ± 12.28) dB,the mean postoperative air-bone gap (ABG) was (9.44 ± 9.62) dB,the postoperative AC and ABG value improved considerably comparing with the preoperative value in all the patients,the difference was statistically significant.CONCLUTION CO2 laser is a suitable and effective adjunct in surgery for ossicular malformations such as otosclerosis.The use of the laser improves hearing results and operation efficiency and is not likely to increase side-effects to patients.
RESUMEN
Objective To discuss the effectiveness of Austrian Combi40+Cochlear Implant.Method Six cases of deaf children implanted Austrian Combi40+Cochlear Implant during the March,2004 to September,2005 were analyzed retrospectively.Result All cases were implanted successfully without complication.All deaf children acquired hearing of some degree when implant devices were operated in one month later.Also All cases were getting their speech intelligibility improved by hearing and speech rehabilitation.Conclusion The effectiveness of Austrian Combi40+Cochlear Implant is related to the age of deaf children with cochlear implant.The early deaf children get cochlear implant and hearing and speech rehabilitation,the better they have speech intelligibility.
